21621600 ÷ 481 
We want to figure out the number of times 21621600 can be divided by 481.

Going ahead to step 1:
2 divided by 481 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 481

Going ahead to step 2:
The number 481 fits into 21 0 times, leaving a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Bring next digit (6) of the dividend behind the 21 and repeat the process: 216 / 481

Step 3:
216 divided by 481 is 0 with a remainder of 216.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 216 after subtracting 0 from 216.
Append the next digit (2) from the dividend to 216 and continue with: 2162 / 481

Moving on to step 4:
2162 divided by 481 is 4 with a remainder of 238.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 1924 from 2162 to get 238.
Append the next digit (1) from the dividend to 238 and continue with: 2381 / 481

Step 5:
481 goes into 2381 4 times with a remainder of 457.
Write down 4 as next digit of the result. 
Result so far: 44.0
Subtract 1924 from 2381 to get 457.
Include the next digit (6) from the dividend after 457, then repeat: 4576 / 481

Going ahead to step 6:
When dividing 4576 by 481, we get 9 with a remainder of 247.
The next digit of our result is 9. 
Result so far: 449.0
The remainder is 247 after subtracting 4329 from 4576.
Bring next digit (0) of the dividend behind the 247 and repeat the process: 2470 / 481

Let's proceed to step 7:
2470 divided by 481 is 5 with a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 4495.0
Deduct 2405 from 2470 and we're left with 65.
Grab the next digit (0) from the dividend, add it to 65, then carry on: 650 / 481

Let's proceed to step 8:
481 goes into 650 1 times with a remainder of 169.
The next digit of our result is 1. 
Result so far: 44951.0
Subtracting 481 from 650 leaves us with 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

Moving on to step 9:
The number 481 fits into 1690 3 times, leaving a remainder of 247.
The next digit of our result is 3. 
Result so far: 44951.3
If we subtract 1443 from 1690, we get 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

Let's proceed to step 10:
When dividing 2470 by 481, we get 5 with a remainder of 65.
Write down 5 as next digit of the result. 
Result so far: 44951.35
Deduct 2405 from 2470 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 11:
If we divide 650 by 481, we get 1 and a remainder of 169.
The next digit of our result is 1. 
Result so far: 44951.351
Deduct 481 from 650 and we're left with 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

Going ahead to step 12:
481 can be fit into 1690 3 times, resulting in a remainder of 247.
Put 3 as the next digit of the answer. 
Result so far: 44951.3513
The remainder is 247 after subtracting 1443 from 1690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

Step 13:
2470 divided by 481 is 5 with a remainder of 65.
Write down 5 as next digit of the result. 
Result so far: 44951.35135
Deduct 2405 from 2470 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Advancing to step 14:
481 goes into 650 1 times with a remainder of 169.
Put 1 as the next digit of the answer. 
Result so far: 44951.351351
Subtracting 481 from 650 leaves us with 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

Going ahead to step 15:
When dividing 1690 by 481, we get 3 with a remainder of 247.
Put 3 as the next digit of the answer. 
Result so far: 44951.3513513
If we subtract 1443 from 1690, we get 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

Moving on to step 16:
If we divide 2470 by 481, we get 5 and a remainder of 65.
Use 5 as the next digit of our solution. 
Result so far: 44951.35135135
Deduct 2405 from 2470 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

The final result is 44951.35135135 with a remainder of 6.5e-08.
